2016-01-12Change function signature passed to cloneYao Qi2-5/+13
I see the following compile error with an old bfin-uclinux gcc to build GDBserver, cc1: warnings being treated as errors gdb/gdbserver/../nat/linux-ptrace.c: In function 'linux_fork_to_function': gdb/gdbserver/../nat/linux-ptrace.c:283: error: passing argument 1 of 'clone' from incompatible pointer type in glibc, clone's prototype is like this, and in uClibc, it is the same, int clone(int (*fn)(void *), void *child_stack, int flags, void *arg, ... /* pid_t *ptid, struct user_desc *tls, pid_t *ctid */ ); so this patch changes function signature from 'void (*function) (gdb_byte *)' to 'int (*function) (void *)'. Note that I find Pedro advised to change argument type from 'void *' to 'gdb_byte *' during the patch review https://sourceware.org/ml/gdb-patches/2013-08/msg00611.html however, I think fix compile error can justify the change back to 'void *'. gdb: 2016-01-12 Yao Qi <yao.qi@linaro.org> * nat/linux-ptrace.c (linux_fork_to_function): Change type of argument 'function'. (linux_grandchild_function): Change return type to 'int'. Change child_stack's type to 'void *'. (linux_child_function): Likewise.

2016-01-12[DOC] Interrupt when program is stoppedYao Qi2-1/+7
This patch changes the document that interrupt (ctrl-c) is not ignored when the program is stopped. When the interrupt was supported in remote target, people thought interrupt is meaningless when the program is stopped. See https://www.sourceware.org/ml/gdb/2005-11/msg00349.html https://www.sourceware.org/ml/gdb-patches/2005-11/msg00307.html recently we find it is hard to preserve this feature "ignore interrupt while program is stopped" when we fix some other bugs. See https://sourceware.org/ml/gdb-patches/2016-01/msg00039.html so we think we can go to the simpler approach "not ignoring ctrl-c when program is stopped". As a result, we tweak the documentation here. gdb/doc: 2016-01-12 Yao Qi <yao.qi@linaro.org> * gdb.texinfo (Interrupts): Update the document on handling interrupt when program is stopped.

2016-01-12sim: mips: workaround 32-bit addr sign extensionsMike Frysinger2-1/+18
The mips bfd will sign extend 32-bit addresses into 64-bit values, so if the entry happens to be 0x80000000 or higher, it is turned to 0xffffffff80000000 which points to memory that doesn't exist. This wasn't an issue until commit 26f8bf63bf36f9062a5cc1afacf71462a as all addresses were automatically truncated there in the translate function to 32-bits. When we cleaned up that code, the full 64-bits were checked leading to many test failures for mips-sde-elf targets and such.
2016-01-11Refactor gold to enable support for MIPS-64 relocation format.Cary Coutant21-690/+1591
For MIPS-64, the r_info field in the relocation format is replaced by several individual fields, including r_sym and r_type. To enable support for this format, I've refactored target-independent code to remove almost all uses of the r_info field. (I've left alone a couple of routines used only for incremental linking, which I can update if/when the MIPS target adds support for incremental linking.) For routines that are already templated on a Classify_reloc class (namely, gc_process_relocs, relocate_section, and relocate_relocs), I've extended the Classify_reloc interface to include sh_type (which no longer needs to be a separate template parameter) as well as get_r_sym() and get_r_type() methods for extracting the r_sym and r_type fields. For scan_relocatable_relocs, I've extended the Default_scan_relocatable_relocs class by converting it to a class template with Classify_reloc as a template parameter. For the remaining routines that need to access r_sym, I've added a virtual Target::get_r_sym() method with an override for the MIPS target. In elfcpp, I've added Mips64_rel, etc., accessor classes and corresponding internal data structures. The MIPS target uses these new classes within its own Mips_classify_reloc class. The Mips64_ accessor classes also expose the r_ssym, r_type2, and r_type3 fields from the relocation. These changes should be functionally the same for all but the MIPS target. elfcpp/ * elfcpp.h (Mips64_rel, Mips64_rel_write): New classes.

2016-01-10sim: move many common settings from CPPFLAGS to config.hMike Frysinger96-2107/+3571
Rather than stuffing the command line with a bunch of -D flags, start moving things to config.h which is managed by autoheader. This makes the makefile a bit simpler and the build output tighter, and it makes the migration to automake easier as there are fewer vars to juggle. We'll want to move the other options out too, but it'll take more work.
2016-01-10sim: drop unused SIM_AC_OPTION_PACKAGESMike Frysinger62-229/+177
This was imported from the ppc sim, but that was only used to control a single file, and that is already governed by the hw models. There's no need to have a sep configure option here, especially since none of the other sims are using it. Even when the code is enabled, there's no runtime overhead.
2016-01-10sim: allow the environment configure option everywhereMike Frysinger73-411/+744
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: allow the assert configure option everywhereMike Frysinger56-54/+626
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order to make the configure flag available, which none of them do. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports.
2016-01-10sim: drop targ-vals.def->nltvals.def indirectionMike Frysinger59-1557/+151
We don't have alternative nltvals.def files, so always symlinking the targ-vals.def file to it doesn't gain us anything. It does make the build more complicated though and a pain to convert to something newer (like automake). Drop the symlinking entirely. In the future, we'll want to explode this file anyways into the respective arch dirs so things can be selected dynamically at runtime, so it's not like we'll be bringing this back.
2016-01-10sim: mips: drop SIM_AC_OPTION_SMP callMike Frysinger3-43/+7
No other port calls this macro directly, and mips has it hardcoded to the default -- disabling smp. In the future we'll enable this for all targets in common code, so tidy up the mips code now.
2016-01-10sim: allow the inline configure option everywhereMike Frysinger79-1006/+1113
Currently ports have to call SIM_AC_OPTION_INLINE explicitly in order to make the configure flag available. There's no real reason to not allow this flag for all ports, so move it to the common sim macro. This way we get standard behavior across all ports too.
2016-01-10sim: drop --enable-sim-{regparm,stdcall} optionsMike Frysinger69-660/+245
These options were never exposed for most sims (just the ppc one), and they are really only useful on 32-bit x86 systems. Considering modern systems tend to be 64-bit x86_64 and how well modern compilers are at optimizing code, these have outlived their usefulness.
2016-01-10sim: drop --enable-sim-cflags optionMike Frysinger66-716/+191
No other sub directory provides such a configuration option, so drop it from the sim dir as well. This cleans up a good bit of code in the process. If people want to use custom flags for just the sim, they can still run configure+make by hand in the sim subdir and use the normal CFLAGS settings.

2016-01-09sim: stop configuring common subdirMike Frysinger4-18/+7
Now that cconfig.h doesn't exist, there's no need to build in the common subdir anymore. We leave the configure/Makefile files in there as there is a helper for developers to generate the nltvals.def file. Once that gets cleaned up in the future though, we can drop the build logic too.
2016-01-09sim: drop common/cconfig.h in favor of a single config.hMike Frysinger99-10674/+11040
The common subdir sets up a cconfig.h file to hold checks for the common code. In practice, most files still end up using config.h instead which just leads to confusion. Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON so we can drop the cconfig.h file altogether. Now there is only a single config.h file like normal.

2016-01-08perf testsuite: python 3 fixesSimon Marchi3-7/+17
There are a few errors when trying to run the performance testsuite with Python 3. This commit fixes them. In Python 2, it was possible to use relative imports (importing a module relative to the current one). In Python 3 it isn't. So I use absolute_import from the __future__ module, which allows Python 2 to behave like Python 3, and use the Python 3 syntax. In Python 3, dict.iterkeys doesn't exist anymore. Using dict.keys is a good compromise in this case. gdb/testsuite/ChangeLog: * gdb.perf/lib/perftest/perftest.py: Change relative imports to absolute. (SingleStatisticTestResult.report): Use dict.keys instead of dict.iterkeys.

GDB only stays in extension language for a very short period in this case, but if ctrl-c is pressed at that moment, python extension will handle the SIGINT, and exceptions.KeyboardInterrupt is shown. Language extension is used in GDB side rather than inferior side, so GDB should only change SIGINT handler for extension language when the terminal is ours (not inferior's).

2016-01-08Check input interrupt first when reading packetYao Qi2-0/+14
Hi, I see timeout in one of several runs of random-signal.exp like this, $ (set -e; while true; do make check RUNTESTFLAGS="--target_board=native-gdbserver random-signal.exp"; done) In about every five runs, we can see a fail, PASS: gdb.base/random-signal.exp: continue ^CFAIL: gdb.base/random-signal.exp: stop with control-c (timeout) after some investigation, I find '\003' may be discarded by GDBserver when it is expecting '$'. In GDB side, both normal packets and '\003' are sent via function send, but GDBserver may receive them at any time, that is to say, in the receive buffer in GDBserver, '\003' may appear before or after normal packet. However, current GDBserver doesn't handle this case. With this patch applied, I don't see this fail in multiple runs. Although there is still timeout fail, that is a different problem, the next patch will fix it. gdb/gdbserver: 2016-01-08 Yao Qi <yao.qi@linaro.org> * remote-utils.c (getpkt): If c is '\003', call target hook request_interrupt.

2016-01-06bfd/arc: Add R_ prefix to all relocation namesAndrew Burgess33-100/+140
The convention within for relocation names is that they start with the string "R_", however, this is not so for ARC for the display names of relocations, however, internally, the names for the relocations types do have the 'R_' prefix. I suspect that the missing 'R_' on the output strings was an oversight, as I can't see any comment to the contrary.
